thermal/drivers/imx_sc_thermal: Fix refcount leak in imx_sc_thermal_probe
of_find_node_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Fixes: e20db70dba1c ("thermal: imx_sc: add i.MX system controller thermal support")
